Permavoid System

Its high strength and integrity allows it to be designed into pavement structures, and means it is ideal for use in projects requiring shallow soakaway, attenuation or detention such as in contaminated ground and in areas with high water tables. When combined with other parts of the Permavoid range, the complete system allows for superior management and improvement of water quality.

Shallower attenuation, detention or soakaway structures are often necessary in the Middle East because the ground at greater depths can present construction challenges. This could be the presence of chemicals or contamination left over from previous land use, underground watercourses or – more commonly in this region – an unusually high water table. A shallow approach is preferable because it does not rely on expensive pumping equipment and also has a reduced environmental impact due to the reduced excavation and work that needs to take place on site.
